Environment-friendly high-pressure water jet dedusting system

Abstract

An environment-friendly high-pressure water jet dedusting system comprises a sedimentation tank, a sewage lifting pump, a membrane treatment device, a negative pressure pump, a high-pressure water pump, a high-pressure water delivery hose and a spray gun. The membrane treatment device comprises a general treatment tank, a partition is arranged in the general treatment tank and divides the inside of the same into a membrane tank and a purified water storing tank, a membrane component for filtering is arranged in the membrane tank, a sewage delivery pipeline is arranged between the sedimentation tank and the membrane tank, and the sewage lifting pump is connected on the sewage delivery pipeline; a purified water delivery pipeline is arranged between the membrane component for filtering and the purified water storing tank, the negative pressure pump is connected on the purified water delivery pipeline, a purified water outputting pipeline is connected between the purified water storing tank and a water incoming port of the high-pressure water pump, and two ends of the high-pressure water delivery hose are connected with a water outgoing port of the high-pressure water pump and the spray gun respectively. By using the environment-friendly high-pressure water jet dedusting system, water pollution is avoided, fresh water resources are saved, and recycling of water resources is realized.

Description

technical field [0001] The invention belongs to the technical field of high-pressure water derusting, and in particular relates to an environment-friendly high-pressure water jet derusting system which uses river water or reclaimed water instead of fresh water and simultaneously recycles derusted sewage. Background technique [0002] Among the existing derusting methods, the high-pressure water jet derusting method is a more environmentally friendly derusting method, which solves the problem of air pollution caused by traditional sandblasting During the process, the high-pressure pump used requires the diameter of solid particles in the water to be less than 5 μm. Therefore, at present, urban drinking fresh water is mainly used as the main body of derusting, and the sewage after derusting is usually discharged directly. In this way, on the one hand, it causes a waste of fresh water resources On the other hand, since the sewage after rust removal contains old coating powder, ...

[0002] Among the existing derusting methods, the high-pressure water jet derusting method is a more environmentally friendly derusting method, which solves the problem of air pollution caused by traditional sandblasting During the process, the high-pressure pump used requires the diameter of solid particles in the water to be less than 5 μm. Therefore, at present, urban drinking fresh water is mainly used as the main body of derusting, and the sewage after derusting is usually discharged directly. In this way, on the one hand, it causes a waste of fresh water resources On the other hand, since the sewage after rust removal contains old coating powder, if it is discharged directly, it will pollute the groundwater or seawater, that is, the problem of water pollution
